Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, specifically to a telescopic anchor temporary support fence for construction. Background Technology

[0002] During construction, temporary fencing is used to demarcate work areas and isolate construction equipment from pedestrian and vehicle access, serving as a crucial facility for ensuring construction safety. Existing temporary fencing typically employs a combination of support frames and barriers, connected to the ground via counterweights, bolts, or simple stakes to maintain its stability.

[0003] However, existing fences have the following problems in actual use: First, most of them are rigid connections, which are not strong enough to withstand impact. When subjected to strong winds or external impacts, they are prone to tipping over, posing a safety hazard. Second, the anchoring method is singular, which is difficult to accommodate different ground conditions (such as muddy ground and hardened ground), resulting in insufficient applicability. Third, some structures are not easy to disassemble and move after being fixed, which affects the reuse of the fences in different construction sites.

[0004] Therefore, there is an urgent need to propose a structurally improved temporary support fence that can quickly adapt to different ground environments through telescopic anchoring and has multi-level adjustment and buffer reset functions, thereby improving the stability and safety of the fence. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic anchor temporary support fence for building construction, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A telescopic anchor temporary support fence for building construction includes a support frame and a baffle. The bottom end of the support frame is provided with a telescopic anchoring component. The telescopic anchoring component includes a telescopic rod that is slidably installed in the vertical direction. The lower end of the telescopic rod extends out of the bottom end of the support frame and contacts the ground, while the upper end is located inside the support frame. The telescopic rod can extend or retract relative to the support frame in the vertical direction to achieve anchoring or storage during construction.

[0008] A further improvement of this utility model is as follows: the bottom end of the support frame is provided with a sliding groove, the telescopic rod slides vertically along the sliding groove, the sliding groove fits and cooperates with the outer wall of the telescopic rod to limit the direction of telescopic movement; the outer wall of the telescopic rod is provided with multiple positioning holes in the vertical direction, and a pin is provided horizontally at the bottom end of the support frame. After the pin is inserted into the positioning hole, the telescopic rod can be locked in multiple stages. The pin is preferably a structure with a spring or snap ring to prevent it from coming out under vibration.

[0009] Furthermore, the lower end of the telescopic rod is detachably connected to an anchor head via a threaded connection. The anchor head can be replaced with a conical, forked, or suction cup type depending on the ground conditions. The suction cup type anchor head consists of an elastic rubber cup body. Air is expelled by downward pressure, and a negative pressure adsorption effect is created by the material's resilience after release. Preferably, a sealing ring is provided at the edge of the cup body to enhance the negative pressure retention capacity. Under standard hardened ground testing, the suction cup type anchor head maintains negative pressure adsorption for no less than 3 minutes; a double-layer rubber edge sealing structure is preferred to improve the duration of adsorption.

[0010] Furthermore, a buffer is provided between the bottom end of the support frame and the top end of the telescopic rod. The buffer is sleeved on the outer wall of the telescopic rod, with one end fixed to the inner wall of the support frame and the other end abutting against the limiting shoulder of the telescopic rod. The buffer can be a compression spring, a rubber ring, or a polyurethane sleeve. The compression deformation of the buffer is 5mm to 20mm under normal working conditions. When the telescopic rod is forcefully inserted into the ground, it deforms to absorb the impact energy and releases energy to push the telescopic rod back to its original position after the external force is released.

[0011] This utility model may also include a driving device, preferably a manual driving method, in which the operator can manually press down the telescopic rod or step on the pedal connected to the upper end of the telescopic rod to make the telescopic rod extend out of the ground along the guide groove, and lock it with the help of the pin.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of telescopic anchor temporary support fence for building construction, by setting telescopic anchor components at the bottom of the support frame, combined with sliding groove guidance, multi-level locking with pins and replaceable anchor heads, can achieve reliable anchoring on different construction ground surfaces and maintain stability under external forces, significantly improving the applicability and safety of the fence.

[0014] 2. This type of telescopic anchor temporary support fence for building construction has a buffer between the telescopic rod and the support frame, which can absorb energy when the fence is impacted and automatically reset after the external force is released, thereby enhancing the impact resistance and service life of the fence.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-8 As shown, this utility model provides a telescopic anchored temporary support fence for building construction, including a support frame 1, a baffle 2, and a telescopic anchoring assembly 3. The baffle 2 is vertically arranged on the outside of the support frame 1, and adjacent support frames 1 and baffles 2 are connected by a snap-fit ​​method, which can be spliced ​​to form a continuous enclosure structure for isolation and protection of the construction area.

[0026] like Figure 2 As shown, a telescopic anchoring assembly 3 is fixedly connected to the bottom end of the support frame 1. The telescopic anchoring assembly 3 includes a telescopic rod 31, which is vertically arranged with its upper end inserted into the interior of the support frame 1 and its lower end extending through the bottom end of the support frame 1 and in direct contact with the ground. The telescopic rod 31 can slide up and down relative to the support frame 1 in the vertical direction, thereby achieving extension anchoring or retraction.

[0027] like Figure 2 and Figure 3As shown, the bottom end of the support frame 1 is provided with a vertical groove 12. The telescopic rod 31 slides vertically along the groove 12. The groove 12 is tightly fitted with the outer wall of the telescopic rod 31 to limit the movement of the telescopic rod 31 to only the vertical direction and prevent lateral deviation. Multiple positioning holes 311 are evenly distributed along the vertical direction on the outer wall of the telescopic rod 31. A pin 13 is horizontally installed through the bottom end of the support frame 1. When the telescopic rod 31 is pushed down, the operator can select a suitable position of the positioning hole 311 and insert the pin 13 into the positioning hole 311 to lock the telescopic rod 31 at different extension lengths. The pin 13 is preferably a spring pin or a retaining pin with a shoulder. After being inserted into the positioning hole 311, it can create a locking effect to prevent it from coming out due to vibration or external force.

[0028] like Figure 4 As shown, the lower end of the telescopic rod 31 is detachably connected to an anchor head 32. The anchor head 32 is fixedly connected to the lower end of the telescopic rod 31 by threads and can be replaced according to different construction ground conditions: A is a pointed cone-shaped anchor head, used for insertion into muddy ground; B is a forked claw-shaped anchor head, used to adapt to soft ground; C is a suction cup-type anchor head, which is made of an elastic rubber cup. When pressed against the ground, air is expelled, and after release, it relies on the material rebound to form a negative pressure adsorption. Preferably, a sealing ring is set on the edge of the cup to enhance the adsorption effect.

[0029] like Figure 5 As shown, a buffer 33 is provided between the bottom end of the support frame 1 and the upper end of the telescopic rod 31. The buffer 33 is sleeved on the outer wall of the telescopic rod 31, with one end fixed to the inner wall of the support frame 1 and the other end abutting against the limiting shoulder of the telescopic rod 31. When the telescopic rod 31 is forced to insert further into the ground by external force, the buffer 33 undergoes compression deformation to absorb the impact energy; when the external force is released, the buffer 33 releases its deformation, pushing the telescopic rod 31 upward to achieve partial reset, thereby improving the overall stability.

[0030] like Figure 6 As shown, one way of using this embodiment is as follows: when the fence is set on the muddy ground, the operator manually or by stepping on the upper end of the telescopic rod 31, so that the telescopic rod 31 slides down along the slide groove 12 until the pointed cone-shaped anchor head 32 is inserted into the mud layer. Then the pin 13 is inserted into the corresponding positioning hole 311 to lock the telescopic rod 31, thereby completing the anchoring of the muddy ground.

[0031] like Figure 7 As shown, another way of using this embodiment is as follows: when the fence is set on hard ground, the operator replaces the suction cup type anchor head 32, pushes the telescopic rod 31 down, so that the suction cup is pressed tightly against the ground, the air is squeezed out and a negative pressure is formed for adsorption, and then the pin 13 is inserted into the positioning hole 311 to lock, thus completing the fixation of the hard ground.

[0032] like Figure 8As shown, in actual construction, multiple sets of support fences can be connected end to end by splicing support frames 1 and baffles 2 to form a continuous closed enclosure structure. The outer surface of the baffles 2 is provided with reflective sheets 21 at intervals along the height direction. They are preferably fixed to the surface of the baffles 2 with screws, which can reflect light at night or in low visibility environments, thereby improving the visibility and safety of the fence.

[0033] In a further embodiment, the telescopic anchoring component 3 is detachably connected to the bottom end of the support frame 1 by bolts 14. When the fence needs to be moved, the operator pulls out the pin 13 to retract the telescopic rod 31, releases the anchor, and then separates the telescopic anchoring component 3 from the support frame 1 by removing the bolts 14, so as to achieve independent transportation and reuse.

[0034] In summary, this utility model, through the structural cooperation and movement relationship between the support frame 1, telescopic rod 31, sliding groove 12, pin 13, anchor head 32 and buffer 33, ensures that the telescopic rod 31's extension and retraction, locking process after extension, and buffering and reset process after being subjected to force all have clear structural support, which can effectively improve the stability and safety of temporary support fences under different ground conditions.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
